The F1A2-4646 provides the highest inductance and saturation current ratings in the shielded F1A2 SMD inductor family, using a 4.6 × 4.6 mm footprint at 1.2 mm or 1.5 mm height. Its larger body accommodates higher energy storage in DC-DC converter output stages and power-choke roles across automotive electronics, industrial power supplies, and commercial equipment where the 3030 and 3838 footprints are insufficient.
